Abstract
The Beckmann rearrangement of 2-acetylthiophene, 5-methyl-2-acetylthiophene, 5-chloro-2-acetylthiophene, and 2,5-dichloro-3-acetylthiophene oxime benzenesulfonates to the corresponding acetamidothiophenes was carried out by heating with an aqueous methanol solution of sodium acetate. This method can be used for the preparative synthesis of 2-acetamidothiophene and 2,5-dichloro-3-acetamido-thiophene.
